COVER Application filed March 17, 1928. Serial Io. 95,244.

This invention relates to container covers and more particularly to covering means for protecting the mouth and neck portions of various forms of containers from contamination. 7

The invention is particularly adapted for use as a sanitary protecting means for the tops of milk or other bottles, and provides a means 'to protect from contamination the edges of the bottle around the mouth thereof and over which the contents are poured out;

According to the present invention a hood formed of plain or treated coated paper, cellulosic substances or other resilient thin sheet material, is provided by forming a pleated flanged portion around a central dlsc-like bod portion. The pleated flanged portion is preferably formed with integral relnforcing means at its edge for also locking or clamping the pleats against separation. The edge reinforcing may be accomplished by 'aspecial chemical treatment of the paper edge or by folding or rolling back the paper to provide a semi-elastic edge. The flanged portion is made of a size to closely embrace the top of the bottle, the bottle if desired being provided either with the conventional rounded "beaded top edge .or lip portion, or with a special beaded portion particularly adapted to engage the hood. With the pleated flange formed with the novel reinforced edge as herein described, a semi-elastic hood is formed of one integral piece of the sheet material,.'and the hood when drawn down over the beaded'ed e of the bottle will engage the bottle with su cientfirmness to prevent accidental removal. In order to protect the cus tome'r or user from pilfering of the contents of the bottle, the hood may beafiixed at one or more points by adhesive material to the bottle neck or rim, or to the cardboard cap or stopper of the bottle. Then, when unauthorized attempts are made to remove .the

become permanently mutilatedor torn out.

The hood cannot thereafter be replaced and restored to normal appearance and pilfering which otherwise would often pass unnoticed will be clearly exposed.

hood, the portion having the adhesive A simple and inexpensive construction is provided for the desired purposes, having a pleasing appearance, and which may be quickly and securely applied and easily removed by the user. The necessity of separate securing means is also eliminated.

Various specific'objects, features and advantages will clearly appear from the detailed description given below taken in connection with the accompanying drawings which form a part of this specification.

In the drawings, Fig. 1 illustrates a side elevational view, partly in section, showing a hood member embodying the invention in one of its forms and as applied to a cream bottle.

Fi 2 is a view similar to that of Fig. 1, but s owing a modified form of construction I embodying the invention.

Fig. 3 is also a view similar to Fig.1, showing a further modification of the invention, and also showing the invention as applied to a cream bottle having a special form of head ed neck portion.

Fig. 4 is a sectional view taken substan- "ti'ally along the lines A-A of Fig. 3, and

Fig. 5 is a sectional view taken substantially along the line B B of Fig. 3.

Referring more particularly to Fig. 1, a milk or cream bottle or other container is indicated at 10. The top of the bottle around the mouth thereof ma be formed with the conventional headed e ge 11, except that the lower ortion of the beaded edge should prefera hly, but not necessarily, terminate as at 12 somewhat more abruptly than'with the conventional shape, thus providin a deep annular recess 13 around the neck 0 the bottle.

The hood member formed of paper or the like, comprises a disc-like body portion 14 for fittin under the conventional form ofcardboar bottle cap 15. Around the periphery ofthe portion 14 the hood member is suitably pleated and drawn upwardly, 9.; outwardl and then downwardly over the edge of t e bottle. In the figure the pleats are desi ated by the numeral 16. This downwar y projecting pleated {portionprovides a depending semi-elastic ange which,

when pressed over the top of the bottle, will closely conform to the shape of the bottle. The flange edge as formed with the pleat clamping means hereinafter described, serves to hold the pleated flange relatively firmly against the bottle and prevents expansion thereof.

Unless secured in some manner, the pleated flange would ordinarily expand, because of its natural resiliency, away from the bottle. In order to inhibit this action and also to provide a reinforcing edge, :1 rolled or beaded I portion 17 is integrally formed at the flange edge. An enlarged sectional view of a suitable form of beaded edge is illustrated in Fig. 4. As here shown the edge portion is wrapped around itself to form a beaded edge of approximately two layers of the pleated paper compactly pressed together. In this manner a relatively firm but somewhat elastic or resilient ring is formed around the edge of the flange. The ring, being formed of the folded or pleated material, is capable of considerable expansion without breaking. The ring or beaded edge portion should preferably be of a diameter slightly smaller than that of the annular grooved portion 13 on the bottle. Accordingly, when the hood is pressed over the mouth of the bottle, the beaded edge together with the pleated side walls of the flanged portion of the hood, will firmly embrace the bottle because of their natural tendency to contract to their normal size. Thehood is thus made sufficiently close fitting for securely engaging the bottle without the use of additional clamping means such as metallic rings or the like which have been heretofore used. Furthermore, although the hood when formed as above described embraces the bottle with suflicient firmness to prevent accidental or unintended removal, the hood may be very quickly and easily removed when it is desired to pour out the contents of the bottle. With the particular form shown in Fig. 1, removal of the hood also causes removal of the cardboard cap.

The embodiment of the invention illustrated in Fig. 2 is similar to that of Fig. 1

. with the exception that a hood member 18 is provided with a top portion which extends over the mouth of the bottle above the usual cap member designated by the numeral 15. An area 18' of this top portion may be depressed and fixed by adhesive material to the cap member 15'. Or if preferred, portions of the hood may be glued to the container itself. Then when unauthorized attempts are made to remove the hood. the portion having the adhesive will become permanently mutilated or torn out and the hood cannot thereafter be restored to normal appearance and pilfering which otherwise might not be noticed, will be clearly exposed.

In Fig. 3 a further embodiment of the invention is illustrated in which a bottle 19 is provided with the conventional form of cardboard cap at 20. In this instance a paper hood member 21 is provided with a body portion 22 stretched over the top of the bottle and with a pleated flange 23 extendin r down over the neck portion of the bottle for a substantial distance. With this form of device, the cap member 20 and the hood member 21 engage the bottle entirely independently and the user, if he desires, may use either the cardboard cap or the hood member separately as temporary covers for the bottle. The flange portion 23 inthis instance preferably extends in a substantially vertical direction at right angles to the body portion 22. The bottle 19 is here provided with a special beaded neck portion 24, the edge of the flange portion 23 being rolled or beaded at 17 as in Fig. 1. The rolled or beaded portion 17 may be drawn down over the bottle and such portion being semi-elastic, may be stretched over the beaded portion 24. and becomes lodged beneath such portion whereby the hood is securely held in place. In Fig. -5 a cross-sectional view taken through the pleated flanged portion is shown. The manner in which the pleats are folded and their relative position with respect to their beaded or rolled edge is indicated.

While the invention has been described in detail with respect to certain particular preferred examples which give satisfactory results, it will be understod by those skilled in the art, after understanding the invention, that various changes and modifications may be made without departing from the spirit and scope of the invention and it is,-

therefore, intended in the appended claims to cover all such changes and modifications.

That which is claimed as new and upon which it is desired to secure Letters Patent 1. A container cover comprising a hood formed of resilient sheet material, having a .Central portion for covering the container month, an integral expansive pleated flange depending from said central portion for closely embracing acontainer neck, the edge portions of said flange being rolled back upon themselves into pleat clamping relation.

In combination, a container having av beaded neck portion adjacent the mouth thereof, a container cover comprising a paper hood covering the container mouth and neck portion and closely conformativc thereto, the edge portions of the hood being pleated and rolled back upon themselves for forming an integral edge which is normally contractive on the container.

3. In combination, a container havin a neck portion adjacent the mouth thereo a container cover comprising a paper hood covering the container mouth and neck portion and closely confo'rmative thereto, the edge portions of the hood being pleated and formed with an integral reinforcing beaded portion for engaging the beaded neck portion of the container whereby the hood is secured thereon, said integral beaded portion comprising a series of'nested tubular elements formed by curling the pleated paper. In testimony whereof I have signed my name to this specification.
